I failed the BCMSN exam 3 weeks ago (717 out of 804). I studied more and I failed it again today (762 out of 804). The one thing I noticed was that on both exams I scored 33% for the STP topic. I believe that I have a very good understanding of the theory of STP and know how to configure STP properly and I feel getting a 33% for this topic on both exams is very unusual for me. Is it possible that the BCMSN exams that I took were graded incorrectly? Has this kind of thing ever happened before? I'm going to be calling Pearson Vue on Monday to see about getting my second exam rescored. I just wanted to know if anyone has ever heard of this before.
